VXA-300 PILOT III OPERATING MANUAL
15
ADVANCED OPERATION
Tuning Methods
Throughout this manual, you will see references to sev-
eral different frequency setting methods. Each will be par-
ticularly useful in a particular operating situation, and they
are described below:
VFO (Variable Frequency Oscillator)
The VFO is a “tuning dial”
system which allows you to
tune through the NAV or COM
bands using the DIAL selector,
the Keypad, or the scanner. The VXA-300 has two
VFOs which are called VFO-A and VFO-B. Press the
[

)]
key momentarily to switch between
VFO-A and VFO-B. You may set VFO-A to the NAV
band, and VFO-B to the COM band, if you like.
MR (Memory Recall)
The MR (Memory Recall)
mode of the VXA-300 pro-
vides the user with the ability
to store and recall as many as
150 channels in the radio’s main memory bank. These
memory channels may also be labeled by you with an
alpha/numeric name of up to 8 characters in length, to
aid in quick identification of the channel. See page 28
for details on creating alpha/numeric labels.
BOOK (Pre-Programmed) Memories
The Book memories are pre-
programmed, either at the fac-
tory or by your Dealer (de-
pending on your country’s re-
quirements), typically including the major COM and
NAV band station frequencies used in your area. The
Book memories can be changed by the user. See page
42 for details.
WX (Weather Channel) Memories (USA version only)
Ten Weather Channels are pre-programmed at the fac-
tory. The VXA-300 will auto-
matically scan this special
bank when it is selected by the
user.
